To all wiwm t ma'y concern:

Be it known that l, HAIOLD Binnen, a citizen of the United States, residing 1n the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Combination-Blower, orn which the following is a specification.

ln moving picture' theaters, it has recently become the practice to install what is commonly termed a moving picture orchestra, the same comprising three distinct elements, the organ element, which must be operated by suitable pressure creating or blowing devices, andthe piano element, and the mechanicals, that is, mechanical instruments, such as snare drums, bass drums and the like, said piano and mechanicals being heretofore operated by a-separate suction creating device. practice to employ a motor coupled to a blower or a pressure creating device for blowing or operating the organ, and asecond motor connected with suction creating or vacuum devices for operating the piano and the mechanicals. This has, consequently, necessitated the employment of two distinct electric motors and two`distinct sets of mechanism for creating the suction or vacuum and the pressure Jfor the above described elements, which has consequently entailed the Aexpense of supplying electricity to two electric motors, and there has, in addition, been a great deal of space taken up by the pressure and suction or vacuum devices` respectively, and in some instances, provision hasA had to be made for a special or additional room for either or both of said suction or vacuum and pressure de,- vices. It has also heretofore been the prac tice in producing the vacuum or suction, to have an electric motorcoupled to aneccentric, which in turn was connected tota feeder, whereby the re uired suction was produced. As these madliines generally run continuously for ai period of ten to twelve or fourteen hours a day, the leather of which the feeders vwere constructed would become liable to crack and open, thus allowing the suction to'be broken, and cause a cessation of operation of the musical instruments sure creating apparatus, it was alsoneces# sary to have a separate motor and a separate pressure creating apparatus, which was ordinarily considerably larger in size, and

lt has heretofore been the.

generally had to have a special compartment, wherein the same could be placed. Furthermore, the ordinary speed of an organ blower is generally 1165 revolutions per minute; consequently, the organ blower would necessarily have to made so large that it would befimpractical, if not impossible, to place it in the average moving picture theater, and, in addition, to the blower being very costly to build, it required a motor of considerable horse power.

By my present invention, l locate the suctionv or vacuum and pressure creating apparatus upon a. single main shaft, which is inclosed in a box or'casing orn novel construction, so as to be rendered practically sound-proof, said casing being provided with a pressure outlet, leading from said casing to the organ, which is in cooperative communication with the pressure creating devices, and l also provide the casing with an inlet or suction connection, whereby suction is created from the piano and the mechanicals, whereby the organ, piano and mechanicals are properly operated at the desired periods.

By my invention, it is only necessary to employ a. single motor, coupled to a single main shaft, upon which a pressure fan and a plurality of suction fans are mounted, 'it being necessary to employ a greater number of suction fans than pressure fans, because three duties are required or three operations performed, by the suction end of the ap- Y paratus: a.-turning the piano roll; d operating the pneumatics;'and 0,-operating the mechanicals.

By my present invention, space is economized, and the expense for electricity is greatly'reduced from what it has been heretofore, because I only employ a single motor and a single main shaft, and since all the operative elements are mounted thereon, there is a constant suction-or vacuum and a constant pressure, dependent upon the speed of rotation of the motor. In addition, the construction of the moving picture orchestra is greatly simplified, since the builder is enabled to utilize the room which was heretofore taken up by the former feeders. actuated thereby. In the case of the pres- It will also be apparent that the matter of the electric motor wirin is much simplified, as itis reduced one-halfg by the employment of a single motor, since it was heretofore necessary to connect up two circuits for two independent motors, whereas in my present invention, only a single motor is employed, and there is, of course, but a single motor to get out of order, as compared with the two motors heretofore employed.

Furthermore, by my present invention, where a combination blower is employed, the same can be placed in a separate room or in some location away from the moving pictureorchestra, which is a great improvenient over prior constructions, as heretofore, it has been generally considered necessary to have the motor inside the pianoor inside the moving picture orchestra, which was dangerous on account of lire, as the motor was necessarilyinclosed in the orchestra casing.

To the above ends, my invention consists of a novel construction of a combination blower, the important features of Which will be hereinafter fully set forth and particularly pointed out in the claims.

For the purpose of illustrating my invention, 1 have shown in the accompanying drawings one form thereof which is at present preferred by me, since it will be found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged ganization 'of these instrumentalities asV herein shown and described.V

Figure 1 represents'a longitudinal, sectional iiew of a combination blower emy bodying my invention, certain of the parts being shown in elevation. F ig. 2 represents a section on line en Fig. 1. Fig'B represents a section on line g/-?j, Fig. 1. Fig. t represents a perspective view of the box in which the principal operative parts are contained, the same being shown in detached position. Fig. represents a sectional view of the pressure creating apparatus. Fig. G represents a sectional view f the vacuum or suction creatingapparatus. Fig. 7 represents a diagrammatic view, showing the manner of connecting up my invention to the organ, the piano and the mechanicals.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1-1 designates the motor, which may be of any suitable type and is mounted upon a plate 2, through which pass the leveling screws 3, which are supported upon the frame or body 4, and provided ywith a series of nuts 5, 6 and i', by the proper manipulation of which, the motor can be raised or'lowered` so that its shaft 8 may properly aline with the main shaft 9 of the combination suction and pressurecreating apparatus. The shafts 8 and gare connected by means of a suitable coupling 10,'and as these parts 'per se form no part of my present invention, a. detailed description thereof will be unnecessary.

11 designates a plurality of standards or bearings supported on the frame 4, in which the main shaft 9 rotates, preferably upon suitable `loall bearings, said main' shaft having secured thereto the vacuum or.suction fans 12, 13, 14, 15 and 16, which in the present instance are five in number, and are separated from each other b v the partitions 17, the partition 18 separating the fan 12 from the end 19 of the inclosing box 20.

All of the Suction fans 12 to 16 are constructed substantially alike. as will be understood from Fig. G, and comprise the hub 21 and the upright disk or body portion 22, having the curved blades 23, against which thedisk or -plate 24 is secured. the latter having the opening 25 for the suction or ingress of the air which enters the port 26, through the suction pipe 27.

28 designates an upper series of blocks, which latter are secured to the upper portions of the partitions 17, as seen in Fig. 1, said blocks having secured thereto the plates 29, the extent and contour of which will be understood from Figs. 1 land 3, similar blocks and plat/cs 30 and 31, respectively, being located in the lower portions of the box 20, as will be understood from Figs. 1 and 3. IThe hubs 21 ofthe suction fans 12 are secured to the main shaft) b vany suitable means, and it will be apparent that as said shaft is rota-ted in the proper direction. the suction or vacuum will be created through the suction inlet 2T, port L6, the suction" fan inlet 25, and the air will pass out the outer periphery of the suction fan 12 and thence around the respect-ive partitions and plates through the other suction fans to the outlet port 32, passage 33 and outlet. port 35g in the manner familiar to those skilled in this. art. rlfhe partitions 35 divide the series of suction fans from the pressure fan 36, which is contained in the pressure chamber 3'?, which is formed by the partitions and 38, to the left'of which latter is located the inlet chamber 39, into which air is drawn from the atmosphere through the ports 40. The construction and location of the pressure fan will be understood from Figs. 1, 2pand said pressure fan having the hub 41, and the plate or disk 42, upon which are cast or otherwise secured the curved blades 43, (see Figs. 2 and 5), to which is secured the plate or disk ed, having the inlet opening 4-5 into which air is drawn through the opening 46, which communicates with the inlet passage 39, the air which is drawn in through the prts 40 being forced through the outlet port 47 into the pressure or outlet nozzle 48 to the desired point. as will be hereinafter explained.

The suction fans 12, 13, ld, 15 vand 16 are meneer substantially alike, and are similai` to 'the pressure fan 36, except that li 'preferably make the latter somewhat larger or of greater power, it being noted that the pressure izan 36 has its inlet at the left, as 'will be understood from the left-hand portion or' Figs. l and 5,while the Suction fans here their inlets at the right, as will be understood from the right-hand portion of Figs. l and G, the conjoint operation of the sues tion fans being' apparent to those skilled in the art, it being noted that ythe suction lansand the pressure are. mounted upon the same main shaft, so that but a single motor is required to operate them.-

` ln carrying out the broad embodiment of my invention, whichcompr'ises the conjoint crcn'tiono2 a vacuum or suction and a pres-A sure within a single casing by combined apparatus mounted upon a common main shaft and actuated by a single motor, whereby a combined or conjoint operation is produced through tbe medium of the motor and single shaft common to the suction and pressure devices, it will be apparent that any desired form of in'closing casing may be employed, so long as the requisite suction and outlet ports and inlet and pressure discharge ports are located in the proper positions with respect to the vacuum and pressure creating1 devices, respectively. l have, however, in the present instance, designed a orrnoi2 inclosing casing, which l preferably employ, the construction ci which may be varied accordance with requirements. 'Iihe hereinbefore described suction and pressure creatingl devices are located in a sectional box 20, best seen in perspective in Fig. t, said boi: being composed of the upper and lower sections 49 and 50, respectively, which are superimposed upon each other and held in as-` sembled position by means of the side strips 5l and end strips 52,v which lutter are secured to the box members, which may be o' wood or similar materiel, in any suitable manner. Around the box 20, l place a layer ol" felt or similar material 53, which surrounds the sides, ends and top of the bon, und around this felt, l place a metallic casing 54. and secure the same to the frame or bed 4 by means of the straps 55. l also secure to theends i9 of the box, angle irons 5G, whose feet 57 are secured to the freine 5iby. any s'uitale fastening devices, as the bolts 58, the locution of said angle irons being understood from Fig. l.

l also secure the ends 19 of the box and their adjuncts in position by means of the long screws 59, :is will be seen in Figs. l and 2i. whereby an exceedingly rigid, efiicient und sound-proof structure is produced, wherein vibration is reduced to a minimum, and which is exceedingly durable.

The trame l is supported upon the bed of felt or similar material 60, best seen in Figs.

1 and S, the latter being supported upon the base 6l, which may be oi' wood or similar material. v

By the employment oit the above-described construction, l'have found that en exceedingly durable and eilicient construction is produced, wherein the obiectionable l" also connect thel suction inlet 27, seen in4 Figs. l and 7, withA the suction pipe 63, which leads from a box 64, having a branch 65, which leads to thcpiano 68, and a branch 6G, which leads to the operating' mechanism for the Inechanicals 69.

ll deem it unnecessary to 'enterinto any detailed construction o" Vthe organ member or the piano or mechenicals shown diagramniatically inflig. 27, the saine form, per se, no part ofthe present invention. also dcem'it unnecessary describe the operi-- tion of these devices further than 'to show that the pressure pipe 6?', conducts the pressure to the vorgan 82, or, in other Words, blows the latter, While by the suction pipe 63, l am enabled to create the necessary suction or vacuum to operate the piano element 68 and the mechnnicals 69 in the customary manner, it being apparent that ll enabled by my novel construction, to attain the desired actuating of the organ, piano and the mechanicals, through the medium of my novel pressure and suction devices, which are contained in a single casing and operated from a common shaft, by a single motor, wherein the expense heretofore incidentto the operation of these devices is reduced or diminished.

lt will be apparent that the rotation of the motor will operate the main shaft 9 and `give to the suction fans l2, i3, 141-, l5 and 16 undpressure ian 36, a steady and constant rotation. and the requisite vacuum and pressure will be created at the desired points and Vfor the desired purposes.

lit will be understood that the partitions 18, 17. and 38 are preferably oi' wood or similar material, and are in substantial alinement above and below the main shaft 9 said partitions being secured to the boi; 20 in any suitable manner, and critending;r across said bon, having' an opening in the middle oi suiiicient size for the main shaft 9 und hubs 2l to pass through. The upper and lower blocks 28 and i0 ure also preferably orP wood,

and secured to the contiguous'partitions i7,- as will be understood rom'lig. i, while the plates 29 and 3l, which are secured to the blocks 28 and 30, are preferably of metal.Y

l have deemed it unnecessary to describe or show in detail the specic manner oi securing the partitions to the blocks and plates in assembled position, as tliis will be appar`= ent to those skilled in tbe art, and may be varied according to requirements.

it will now be apparent that l have devised a novel and useful construction ci a combination blower, which embodies tbe `features ot advantage enumerated as desirable in vtbe statement of the invention and the above description, and while l have, in the present instance, shown and described a preferred embodiment thereof which be found in practice to give satisfactoryand reliable results, it is to be understood t at 'tbe same is susceptible oi" .modiiication in `various particulars, Without departing from the spirit or scope o'tlie invention or sacrii'icing any of its advantages.
